python实例31[My Stock Info]

本程序使用python3.1实现的一个运行于Windows的控制台小程序，用来显示你所关心的股票的实时价格。

1）每隔一分钟跟新一次，当然你可以改为更短的时间间隔；

2）控制台彩色显示的python模块为WConio，需要单独下载：http://newcenturycomputers.net/projects/wconio.html

3）webservice来源于sina，感谢sina，例如http://hq.sinajs.cn/list=sh600547，返回的结果如下：

var hq_str_sh600547="山东黄金,51.02,51.00,52.71,52.86,50.68,52.70,52.72,16389139
,850524809,3000,52.70,52500,52.69,100,52.67,28849,52.66,7400,52.65,1200,52.72,43
77,52.75,11200,52.76,20000,52.77,4000,52.78,2010-12-31,15:02:06";

4) 也可以使用其他的股票web service （http://www.webxml.com.cn/WebServices/ChinaStockWebService.asmx/getStockInfoByCode?theStockCode=sh600547），返回的结果如下：
